. to controlled electrotherapeutic machines.

My primary object is to provide improved mechanism for closing the battery-circuit when a current is desired; and a further object is to provide improved means for causing an increase in current and to cheapen and simplify the construction of machines of this class.

In the preferred construction there is employed a removable mechanism board or y standard which may be inserted in or removed from the casing at will.

In the accompanying drawings, Figurel is a view in front elevation of a machine embodying my improvements, a portion of the casing being brokenaway to disclose a spring contactmaker; Fig. 2, a transverse section through the mechanism-board, taken as indicated at line 2 of Fig. 3; Fig. 3, a view of the rear side 3 of the mechanism-board and showing the con- 3o nected mechanism andwires, a fragment of the casing also being shown; Fig. l, a transverse section taken at the corresponding line of Fig. 3 and showing the connection between the operating-lever and the magnetic shield for the solenoid-core; Fig. 5, a view of the rear side of the mechanism-board with certain parts of the mechanism removed and certain parts shown in section, and Fig. 6 a view showing the parts of the mechanism at the lower portion of the mechanism-board occupying a different relative position from their position in Fig. 5.

A represents the casing, which may be of any suitable form and adapted to receive on the inner side of its front the removable mechanism-board employed, said casing preferably being supplied at its front with a dialopening a for receiving that portion of the dial which is removable with the mechanism board; B, a mechanism-board provided on its front surface with a dial part b and having secured to its rear surface the principal working parts; 0, a fixed metallic handle secured to the casing A and in electrical connection with a contact-point c on the inner surface of the casing; D, a hand-lever pivotally connected to the board B by a screw 61; D, a spring serving to hold the outer end of the hand-lever normally elevated; E, a dial-pointer post provided with a sprocket-wheel e; E, aspring, one end of whichis connected with a sprocketchain c, which passes about the wheel 6, and

is connected at its free end through the medium of the link 6 with the hand-lever D; F and G, blocks fixedly secured to the board B; 65 H, a vertical standard or post supported by said blocks; I, a solenoid supported from the block said solenoid being provided with a soft-iron core f, which projects downwardly from a metallic plate f, secured to the upper surface of the block F; J, a circuit-interrupter for the primary circuit; K, a fixed contact or switch point for the primary circuit; K,

a movable contact-point for said circuit; L, a movable bar provided with a projection g, of insulating material, which serves to move the contact-maker K; M, a frictionally-operated thrust-bar; M, a support for certain of the movable parts, the same being preferably stamped from sheet metal and fixedly secured to the board B M a lever pivotally connected by a pin h to the support M and by a pin it to the thrust-bar M and provided at its free end with a pin 712 for engaging the recess h adjacent to the inclined surface It on the bar L; N, a tubular magnetic shield inclosing the soft-iron core of the solenoid; N, a vertically-movable plunger-bar secured in guides it is, the latter of which is provided with an adjusting-screw 10 N a link pivotally con- 0 uected at a point Z with the lever D and at a point Z to the bar N; N an angle connectingbar firmly secured at one end to the bar N and carrying at its opposite end a spring contact-pointm and secured firmly intermediate of its ends by a collar m to the shield N; I N

a metallic rod forming a downward projection from the shield N, with which it moves; N

a wire wound upon the post H and with. which the spring-point m is in sliding contact dur- I00 ing themovement of the lever D; N, a wire connecting the wire N with a metallic piece N to which the contact-point K is connected, and Pa coin-chute,transversely through the lower end of which extends the bar L, said coin-chute being provided with an offset P, into which the coin passes after striking the bar L.

The primary circuit isfrom the battery Q through a wire 4% to the interrupter J, from the interrupter J through the wire n to the solenoid, from the. solenoid through a wire 11 to a spring contact-point 02 from the contact-point n through the rod N to the sliding contact-point m, from the contact-point m to the wire N thence through the wire N and metallic piece N to the movable contactpoint K, and from thence when the circuit is closed through the contact-point K and wire n to the battery.

The induced current is from the solenoid through a wirep to a spring contact-point 10', secured to one edge of the board B, thence to the contact-point c on the inside of the easing, thence through the handle 0 to the body of the patient, thence back through the handlever D to a spring contact-point 10 which is secured to the board B and provided with a perforation to receive the pivot d, and'thence through a wire p to the solenoid.

As shown in Fig. 5, the lower end of the bar N is provided with an inclined surface q, and the adjacent end of the barM is movable between lugs q q?. normally to hold the bar M in contact with the bar N. movable in slots r r in projections on the support M. vided with an inclined surface r which is engaged by the lug g on the bar L when the lat- A spring g serves;

A spring r serves 1 to hold the bar L normally retracted, and a spring 1, contacting. with one wall of the slot 0", tends to hold the recessed end of the bar- L in any position in which itis placed. The support M is provided with a bracket T in Y which is journaled a roller 1', located in the path of the inclined'surface h 'of the bar F. Assuming the mechanism-board'to be prop erly located in itsfcasing and the parts properly connected the free end of the bar L may be depressed by droppinga'coin into the tube P. After striking the free end of said bar: and depressing it the coin rolls from the bar:

distance, after which the free end'of said engagement with the contact-point K; During the movement last mentioned the con tact-point m slides along the coiled wire N and cuts the coils thereof in succession from the primary circuit. When the hand-lever D is released, it returns to its original posi' tion under the force of the springs connected with it, and in the return movement the end of the bar M adjacent to the bar Nis frictionally engaged and lifted by said bar N. This movement serves to imparta further longitudinal movement to the thrust-bar, thereby giving to the lever M an additional movement sufficient to carry the inclined surface of the bar L up onto the roller 1", whereby the free end of said bar L is lifted and disengaged from the pin h As soon as the bar N has risen tosuch a height that the adjacent end of the th-rust baragain passes onto theinclined surface q the lower or free'end of the thrust-bar again drops upon the lug g.

In Fig. 3 the recessed'endof the bar L is shown in position to be depressed bya coin. *It is held in this position by thespri-ng Wengaging a wall of the slot in which said-' bar moves. In Fig. 5the'recessed end of'the'bar L is shown interlocked with a pin h, and it is frictionally held in this position by the spring r until released'in the manner shown in Fig. 6. The full lines show the position of the'bar L when the hand leverD'is-in its 'elevatedposition, and the dotted lines show the position of said bar whenthe hand-lever is in its lowermost positions Fig. 6 shows the position ofsaid bar just prior tol'he-instant when the friction end of the thrust-bar passes-from the vertical edge ofthe frictionbar to the inclined surface q during-the-npward movement of the le-ver D:

The use of the tubular magnetic shield for the solenoid-core is well understood, and it will also be readily understood'th'at the'interrupterJ is located in the position sho-wnin dium of the sprocketwheel and sprocketchain shown the pointer is moved over the dial in a manner now understood in the art.

Changes in details of construction within the spirit of my invention may be made.
